Manufacturing method of deco glass panel and glass panel using the same

Abstract

A deco glass panel including a mother substrate formed of glass, a glass powder layer welded on the mother substrate and a rear surface pattern disposed on a rear surface of the mother substrate, wherein the rear surface pattern is located within an outline of the glass powder layer when viewed from the front surface of the mother substrate.

What is claimed is: 
     
       1. A deco glass panel, comprising:
 a mother substrate formed of glass; 
 a glass powder layer welded on the mother substrate; and 
 a rear surface pattern disposed on a rear surface of the mother substrate, 
 wherein the rear surface pattern is located within an outline of the glass powder layer when viewed from the front surface of the mother substrate, 
 wherein the glass powder comprises, by weight, 11-20% SiO 2 , 30-35% ZnO, 15-20% B 2 O 3 , 10-18% Na 2 O, 1-5% Al 2 O 3 , 1-4% ZrO 2 , 1-4% CaO, 0.05-0.25% Fe 2 O 3  and 0.001-0.004% MnO and other impurities. 
 
     
     
       2. The deco glass panel of  claim 1 , wherein the glass powder further comprises, by weight, 0.05-0.25% Fe 2 O 3  and 0.001-0.004% MnO. 
     
     
       3. The deco glass panel of  claim 1 , wherein a film layer is additionally provided on a rear surface of the rear surface pattern. 
     
     
       4. A deco glass panel, comprising:
 a mother substrate formed of glass; 
 a glass powder layer welded on the mother substrate; and 
 a film disposed on a rear surface of the mother substrate, 
 wherein the film has a prescribed surface pattern with a different color from a ground color of the film and the rear surface pattern has the same shape of the glass powder layer, 
 wherein the glass powder comprises, by weight, 11-20% SiO 2 , 30-35% ZnO, 15-20% B 2 O 2 , 10-18% Na 2 O, 1-5% Al 2 O 3 , 1-4% ZrO 2 , 1-4% CaO, 0.05-0.25% Fe 2 O 3  and 0.001-0.004% MnO and other impurities. 
 
     
     
       5. The deco glass panel of  claim 4 , wherein the prescribed surface pattern is formed to be within an outline of the glass powder layer when viewed from an upper surface of the mother substrate.
